When you swap diskettes this way, it is a good idea to write-protect the original diskette so you don’t accidentally write over it. (See “Write-protecting Diskettes” on page 3-15.)

Using a Hard Disk

The removable hard disk in your computer has been prepared for use at the factory. It also may have MS-DOS and Windows installed. If you plan to use MS-DOS or Windows, you can install your application programs and begin work. See the documentation that came with your programs for instructions.

Follow these precautions to protect your hard disk from damage and to avoid losing data:

Never turn off or reset the computer when the hard disk drive light is on. This light indicates that the computer is copying data to or from the hard disk.

After turning the power off, wait 20 seconds before moving the computer. This allows the disks in the drive to stop spinning and the hard disk read /write heads to lock in place so you do not damage the drive.

Never remove the hard disk drive when the computer is on.

Backing Up the Hard Disk

Although the hard disk is very reliable, be sure to back up your files onto diskettes in case you lose some data accidentally. Make copies of all your system and application program diskettes before copying the programs to the hard disk.
